EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 4548-4 testing. ISO 4548-4 is part of the ISO 4548 series of standards regarding testing methods for full-flow lubricating oil filters used in internal combustion engines.
In particular, ISO 4548-4 focuses on the determination of initial particle retention efficiency, lifetime and cumulative efficiency using a gravimetric method. These tests are important to evaluate the performance and effectiveness of oil filters in removing contaminants from lubricating oil.
The primary purpose of ISO 4548-4 is to evaluate the efficiency of full-flow lubricating oil filters in capturing and retaining particles in the oil. The standard is used to determine the filter's initial particle retention efficiency, service life, and cumulative efficiency over time.
ISO 4548-4 provides guidelines for testing the filter's ability to capture and retain particles in lubricating oil when the filter is brand new (i.e., initial particle retention efficiency). This is an important measure of the effectiveness of the filter at the beginning of its service life.
The gravimetric method involves weighing the particles that the filter collects over time. The change in weight is used to calculate the efficiency of the filter in retaining particles.
These standards are important for manufacturers and users of internal combustion engines and lubrication systems to ensure that filters effectively protect the engine by retaining contaminants in the lubricating oil. It helps with quality control and selecting the right filter for specific applications.
